Prenatal Supplementation Research

Description

When viewing vitamins and minerals, it is seen that they are essential for human life and vital for pregnancy. When paired with a healthy diet, prenatal supplements can allow for a healthy pregnancy and reduced maternal and infant health problems.

When viewing vitamins and minerals, it is seen that they are essential for human life and vital for pregnancy. When paired with a healthy diet, prenatal supplements can allow for a healthy pregnancy and reduced maternal and infant health problems. Within this thesis, I was able to break down each vitamin and mineral necessary for a healthy pregnancy and birth. Further, I had the opportunity to dive into the addition of Omega-3 Fatty Acid during pregnancy to add more evidence to the study.

Regulation Of Genes Involved In Skin Repair By Lipid Compounds With Implications For Psoriasis Treatment

Psoriasis is a skin disease that affects millions of individuals. Genetic risk factors for psoriasis include a common deletion of two late cornified envelope (LCE) genes (LCE3B and LCE3C) located within a cluster of genes expressed during epithelial differentiation and skin repair. It was previously discovered that treatment with 1,25-dihydroxyvitamin D3 (1,25D) or analogs thereof can improve psoriasis symptoms in many patients, but the molecular mechanisms for this action are largely unknown. Our laboratory previously showed that 1,25D as well as low affinity ligands for the vitamin D receptor (VDR), such as delphinidin and cyanidin, are capable of upregulating the remaining LCE3A, -3D, and -3E genes to potentially compensate for the loss of LCE3B and -3C in promoting skin repair. In the current study, DHA and curcumin were tested and found to also upregulate LCE3 transcripts in a dose-dependent manner. To investigate other potential target genes for 1,25D and DHA, we tested JunB, for which low or absent expression has been reported to cause or be associated with psoriatic lesions. Our experiments showed a trend for an upregulation of JunB mRNA after DHA treatment, potentially providing benefit for psoriasis patients. Although our hypothesis is that DHA functions as a vitamin D receptor ligand to mediate upregulation of JunB and LCE3 genes, other investigators have assumed that DHA actions in skin are mediated via PPAR isoforms. We therefore utilized a selective ligand for PPAR delta (GW501516) to determine whether PPAR delta, the primary PPAR isoform in keratinocytes, is a mediator of DHA-induced LCE3 gene activation. Although a modest upregulation of LCE3 genes was seen after treatment with GW501516, our findings are still consistent with DHA acting primarily as a VDR ligand. Our results not only provide additional information about the ability of VDR ligands to upregulate specific skin genes with relevance for skin repair, but also may help provide a molecular basis for testing improved treatments for mild to moderate psoriasis.

Fish oil supplementation and cardiovascular disease risk in individuals of blood type A and blood type O

The omega-3 fatty acids in fatty fish and fish oil, eicosapentanoic acid (EPA) and docosahexanoic acid (DHA), have been associated with a reduction in risk for cardiovascular disease. Blood type is a known contributor to risk for cardiovascular events. This

The omega-3 fatty acids in fatty fish and fish oil, eicosapentanoic acid (EPA) and docosahexanoic acid (DHA), have been associated with a reduction in risk for cardiovascular disease. Blood type is a known contributor to risk for cardiovascular events. This study evaluated the effect of fish oil supplements on cardiovascular risk markers in adults with blood types A or O. An 8-week parallel-arm, randomized, double-blind trial was conducted in healthy adult men and women with either blood type A (BTA) or blood type O (BTO). Participants were randomized to receive fish oil supplements (n=10 [3 BTA/7 BTO]; 2 g [containing 1.2 g EPA+DHA]/d) or a coconut oil supplement (n=7 [3 BTA/4 BTO]; 2 g/d). Markers that were examined included total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), high-sensitivity C-reactive protein (hsCRP), and hemoglobin A1C (HbA1C). Results indicated that the percent change in LDL cholesterol was significantly greater in the coconut oil group vs the fish oil group (-14.8±12.2% vs +2.8±18.9% respectively, p=0.048). There were no other significant differences between treatment groups, or between blood types A and O, for the other cardiovascular risk markers. Further research with a larger and more diverse sample may yield a more conclusive result.
